譬如,你有一个函数 让你去找最值问题,那么f(x,y)和g(x,y,z) 就是‘适应度函数’;然后你需要找的x、y、z就是蝙蝠的位置xi的分量。 这就理解了xi的‘维度’问题。2维=(x,y);3维=(x,y,z);4维=(x,y,z,k); 换个马甲,xi的‘维度’问题。2维=(xi-1, xi-2);3维=( xi-1, xi-2, x...

Bat Algorithm (BA) is one of the newer additions in the field although it has been applied in a series of evaluation tests. The method is trying to replicate the echolocation behavior of bats with artificial ones. In this paper, we apply BA to the well-known problem of economic load ...
Bat algorithm (BA) is a recent metaheuristic optimization algorithm proposed by Yang. In the present study, we have introduced chaos into BA so as to increase its global search mobility for robust global optimization. Detailed studies have been carried out on benchmark problems with different chaot...
